Abstract (en)

[origin: EP2111081A2] A method for improving a Radio Resource Control (RRC) Connection procedure in a user equipment (UE) of a wireless communication system is disclosed. The method includes steps of performing an RRC Connection procedure (402), and resetting or re-establishing a lower layer protocol entity for Signaling Radio Bearers (SRBs) when a cell reselection occurs (404).
